parts and functions
It is powerhouse of the cell, makes ATP
What is the mitochondria?
It is formed through electrical force between oppositely charged ions.
What is an ionic bond?
Movement of water across a semipermeable membrane with and area of lower water concentration.
What is osmosis?
Strengthens and protects the cell.
What is a cell wall?
The variable that is manipulated.
What is the independent variable?
The control center of the cell, contains DNA.
What is the nucleus?
When atoms share a pair of electrons.
What is a covalent bond?
The diffusion of molecules across a membrane through transport proteins.
What is facilitated diffusion?
Produces protein for the rest of the cell to function.
What is the rough ER?
The outcome factor; the variable that may change in response to manipulations of the independent variable.
What is the dependent variable?
It makes proteins.
What are ribosomes?
The attraction between a slightly positive hydrogen atom and a slightly negative atom.
What is a hydrogen bond?
The movement of materials through a cell membrane using energy
What is active transport?
Used as storage.
What is a vacuole.
A variable that is not changed.
What is a controlled variable?
It contains chlorophyll which absorbs light energy for photosyntheis.
What is chloroplast?
Unequal sharing of electrons.
What is a polar covalent bond?
The process of taking liquids or fairly large molecules into a cell by engulfing them in a membrane.
What is endocytosis?
It helps keep the shape of the cell.
Measurement system used to indicate the concentration of hydrogen ions (H+) in solution; ranges from 0 to 14.
What is a pH scale?
It digest/break down food, waste, and broken parts.
What are lysosomes?
A covalent bond in which the electrons are shared equally by the two atoms.
What is a nonpolar covalent bond?
The release of substances out of a cell by the fusion of a vesicle with the membrane
What is exocytosis?
Regulates what enters and leaves the cell.
What is the cell membrane?
Does not have a nucleus or other membrane-bound organelles
What are prokaryotic cells?
